摘　　要：本文围绕低截获概率雷达信号处理的特点和实时性的要求,设计了基于FPGA和DSP传统组合模式的LPI雷达信号检测处理平台。在一款基于Keystone构架的多核DSP处理板上,创新性地运用并行关联流水线体系结构和多层任务调度分配信号处理机制,构建了针对LPI雷达信号从预处理到检测结果输出的一整套信号处理模型。经过仿真实验验证,该信号处理模型适合在低信噪比条件下对LPI雷达信号进行检测,且系统资源分配合理占用逻辑资源少,具有实时检测LPI雷达信号的潜力。According to the characteristics of LPI radar signal processing and the real-time requirement, the article designs a LPI radarsignal detection processing platform based on FPGA and DSP. On a multi-core DSP processing board based on Keystone, we use parallelconnection pipeline architecture and the multilayer distribution of task scheduling to process the LPI radar signal. The design builds awhole set of model of I.PI radar signal processing from the pretreatment to the output of detection result. The simulation experiment results show that the signal processing model is suitable for low SNR of LPI radar signal detection, the system resource allocation is reasonable and takes fewer logical resources. The model has great potential of real time detection of LPI radar signal.
